[jira] [Commented] (TAP5-53) Mechanism to send pointers to
serialized data to the client, not the data itself
[ https://issues.apache.org/jira/browse/TAP5-53?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13149686#comment-13149686 ]
Robert Andersson commented on TAP5-53:
--------------------------------------
This issue came up during a security review of the Tapestry based project I'm currently working on.
I have to agree with Josh Canfield over, why reinvent the wheel, what's wrong with storing all of this in the session?

> Tapestry has the capability to store much data on the client, whether it is persisted page fields, or Form component action data. This presents a couple of problems; first, it inflates the size of the rendered HTML stream. Second, it is a potential security issue, since a hyper-intelligent black hat might find a way to change such data before returning it.
> What if Tapestry stored the associated bytestreams on the server, and provided, in the HTML, just a relatively short pointer (a string id that points to the correct bytestream) to the stream?
> A small amount of additional data on the server side could be used to authenticate the pointer, using the user's session id (if a session exists) and host ip.
> Unreferenced data would be periodically purged.
